I often feel the same way. I had someone ask me to make a microservice on some platform she built. I was told it would take 10 minutes. In reality, it took a couple weeks, and then every week for a year I was getting told something was changing and I had to mess with this or that, and also attend daily meetings about the project. 10 minutes turned into 30% of my whole year. The whole platform she built lasted maybe 2 years before it was decided we needed to move on from it. It was a total waste of time.

Meanwhile, I have a little LAMP project that is used significantly more than the micro service, that I’ve run for 15 years that I only have to touch when it needs feature updates. The platform itself just works. Occasionally I’ll need to move to a newer OS, which takes a few hours to get the new server built, run the job to configure it (doing it manually doesn’t take too much longer), then submit a request to change the load balancer to point to the new servers.

Granted, some of this comes down to experience. However, needing to know all the tools involved for the microservice was much more annoying and they broke half the time.
